Abstract

This study aimed to investigate key aspects of the reproductive biology of common sole (Solea solea) and assess the gonadal development in females through the macroscopic examination of the ovary. Monthly sampling was carried out during the entire year of 2019, in the context of the Data Collection Framework (DCF, EU Regulation 2017/1004). A total of 438 samples (N=311 female and N=127 males) of S. solea were collected from commercial landings by the fishing fleet of Ancona (Central Adriatic Sea). Ovaries were classified macroscopically following a four stages maturity scale derived from the Brown-Peterson’s (2011)and suitably modified. The obtained results evidenced that the spawning period was from September to January. The monthly sex ratio was consistently in favour of females, which outnumbered males especially in the largest length classes (total length > 25 cm). The length at first maturity for females was estimated at 22.98 cm.
